Mann Filter W 1170/9 Oil Filter

MANN-FILTER W 1170/9 Oil Filter

The MANN‑FILTER W 1170/9 is a high‑performance oil filter engineered specifically for heavy‑duty vehicles such as trucks, buses and other commercial transport applications. Designed with the demanding operating conditions of large engines in mind, this filter delivers exceptional protection against contaminants while maintaining optimal oil flow.

Key Design Features

• Robust Construction: The filter housing is built from durable materials that resist deformation under high pressure and temperature. This ensures a reliable seal throughout the service life of the vehicle.
• Advanced Filter Media: Inside, a multi‑layer filtration system captures particles as small as 0.5 µm, protecting engine bearings, pistons, and valves from wear and corrosion.
• High Flow Capacity: The filter’s design allows for low pressure drop, which preserves engine efficiency and reduces fuel consumption.
• Integrated Return Valve: A built‑in non‑return valve prevents oil backflow during shutdown or when the vehicle is in neutral, ensuring consistent lubrication.
• Threaded Mounting (M30x2): The filter uses a standard M30×2 thread size, making it compatible with a wide range of heavy‑duty engine housings without requiring adapters.

Compatibility and Applications

The MANN‑FILTER W 1170/9 is specifically tailored for large displacement engines found in:

• Commercial trucks with diesel or gasoline powertrains.
• Long‑haul buses and coaches.
• Utility vehicles such as construction equipment, forklifts, and agricultural machinery.

Its design accommodates the high oil volumes and extreme operating temperatures typical of these engines, ensuring reliable performance under both normal and heavy‑load conditions.

Installation Guidelines

1. Preparation: Ensure the engine is cool before starting. Drain any residual oil from the filter housing to avoid contamination during installation.
2. Cleaning: Clean the mounting surface with a lint‑free cloth and mild solvent to remove dust or old gasket material.
3. Gasket Placement: Place a new, factory‑approved gasket on the filter face. Avoid over‑tightening which can damage the seal.
4. Screw Insertion: Thread the filter onto the housing by hand until it is snug, then tighten with a torque wrench to the manufacturer’s specified value (typically around 30 Nm for M30×2).
5. Check for Leaks: After installation, start the engine and inspect the filter area for any signs of oil leakage.

Performance Benefits

• Extended Engine Life: By trapping fine particles, the filter reduces wear on critical components, leading to longer service intervals.
• Improved Fuel Efficiency: Low pressure drop maintains optimal oil flow, which helps keep engine friction and fuel consumption at minimal levels.
• Consistent Lubrication: The return valve ensures that oil remains within the system even when the vehicle is stopped or idling for extended periods.
• Reliability in Harsh Environments: Whether operating in dusty construction sites, hot climates, or cold winter conditions, the filter maintains its integrity and filtration capacity.

Maintenance Recommendations

For vehicles that operate under heavy load or in contaminated environments, it is advisable to replace the MANN‑FILTER W 1170/9 every 10,000–15,000 km (or as per the engine manufacturer’s service schedule). Regular inspection of the filter housing and gasket during routine maintenance helps detect early signs of wear or damage.
